2x11 - Charlie and Lola

Charlie and Lola are planning to put on their very own circus show. Lola wants to do forward rolls for the show, but is having trouble doing them without Charlie's help. They head to the park to practice their show and then Charlie plays some football with Marv. Lola hears Charlie crying and finds that he's hurt his arm. At first, she's upset when he can't do anything, but then she finds the perfect way to help him.
